most of these cars leak oil on the motor mount. oil breaks down the rubber and the mount falls apart. mine was so gone the engine and tranny would twist in the bay when shifted from p to D or d to r.
the trans mount you can look at it, at the top part will be a round button sticking up through the metal top part of the new mount. on the new one its flush with the metal. raised button shows how much its compressed over time.
